FIREARM.

Specification of Letters Patent.

Patented Nov. 9, 1920.

Application filed January 30, 1918. Serial No. 214,551.

T 0 all whom it may concern Be it known that I, KLAAs JoHAN PEN, a subject of the Queen of the Netherlands, teacher, residing at The Hague, the Netherlands, have invented certain new and useful Improvements in Firearms, of which the following is a specication.

This invention relates to improvements in sighting devices for firearms and the principal object of the invention is to provide an improved construction by the means of which firearms may be accurately aimed at night.

For the purpose of night shooting it has heretofore been proposed to provide the rear side of the ordinary front sight with a luminous spot, and the rear side of the ordinary notched rear sight with two luminous spots, which are arranged on opposite sides of the rear sight notch. With this known construction, the shooter must not alone view the luminous spot of the front sight between the sides of the notch in the rear sight, but he must also maintain the two luminous spots of the rear sight in alinement with the spot of the front sight.

Another object of this invention is to improve the known construction and to provide sighting means which will render night shooting easier and more accurate.

With the foregoing objects outlined and with other objects in view, which will appear as the description proceeds, the invention consists in the novel features hereinafter described with reference to the accompanying drawing and more particularly pointed out in the appended claims.

Referring to the drawing Figure 1 is a rear view of the known sighting device for night shooting.

Fig. 2 is a rear view of my improved front sight.

Fig. 3 is a rear view of my complete sighting means and illustrating the manner of using the same.

Fig. 4 is a perspective view of a portion of a firearm showing my improved front sight applied to the barrel.

The known sighting means for night shooting is shown in Fig. 1, and in this figure a designates the ordinary front sight provided on its rear side with a luminous spot (Z. Z) designates the ordinary rear sight having the usual notch and provided at opposite sides with luminous spots 6 and f. The spots 6 and f are in alinement with a line drawn parallel to the upper edge of the rear sight and when the firearm is properly aimed these spots 6 and f are in alinement with the spot d. 0 represents the target and in use the sighting means are presumed to occupy the positions shown in Fig. 1. WVith the known construction, the shooter must not only view the spot (l in the center of the notch but he must also place the spots 6, (Z and f in alinement.

Referring now to Figs. 2 and 3, b represents my improved front sight, which, for night shooting, is placed just in the rear of the ordinary front sight. This sight is provided with a ridge 1", which is located between two notches r and has a fiat top r Thisridge is of the same height as the ridge or point of the ordinary front sight and it conceals the ridge of the ordinary sight, when the sight I) is viewed from the rear. The ridge 1" is provided with a large luminous spot it and the sight 7) has two wings r located on opposite sides of the ridge 1" and each carrying one luminous spot m, 'n. The upper edges of the wings r are flat and are arranged in alinement with the fiat top of the ridge 1" and the spots h, m and n are arranged in alinement with a line drawn parallel to the flat edges of the ridge 1 and wings W.

In conjunction with my improved front sight I), I employ a notched rear sight 6 having parallel side posts 70 and Z.

As shown in Fig. 3, to sight the firearm, the shooter first views the three shots h, m and n in the positions shown by dotted lines above the upper edge of the rear sight 5 Then he causes the front sight Z) to descend to the position in which the flat top of the ridge 1 is in alinement with the flat upper edge of the rear sight 5 and the spot it is central of the notch in the rear sight. In this position the firearm is accurately aimed for firing.

The side posts is and Z enable the rifleman to obtain a broad view between the front and rear sights, so that the gun may be aimed with the same accuracy as if the ordinary sights were employed during daylight shooting. WVith my construction, the rifleman will require but little practice to enable him to shoot as accurately at night time as he can with the ordinary sights in the daytime.

It is obvious that more than three luminous spots may be provided on the front sight. However, three spots are sufficient for thepurpose set forth.

hat I claim and desire to secure by Letters Patent is:

1. A firearm having a barrel provided with a notched rear sight, having a front sightmounted on the barrel forward of the rear sight and provided with a plurality of spaced liminous spots on its rear side and another luminous spot arranged on the rear side of the front sight midway between the first spots.

2. A firearm as defined in claim 1, in which the spots are arranged in a straight line perpendicular to the symmetry plane of the firearm.

3. A firearm having a barrel provided with a notched rear sight, a front sight mounted on the barrel forward of the rear sight and provided with three luminous spots arranged in a staight line perpendicw lar to the summetry plane of the firearm, the central spot being somewhat larger than the other spots and being arranged in alinement with the symmetry plane of the firearm.

4. A firearm having a barrel provided with a notched rear sight having parallel side posts extending above the upper edge of the sight and a front sight mounted on the barrel forward of the rear sight and provided with a plurality of luminous spots.

5. A combination as defined in claim 1, in which the front sight is provided with a ridge having a straight upper edge, one of said spots being located directly beneath the upper edge of said ridge.

6. A firearm having a barrel provided with a front sight including a plate having a plurality of spacednotches provided in its upper edge and dividing the upper por tion of the plate into a ridge and a plurality of side wings, luminous spots provided on the ridge and wings, a rear sight having a notched edge, and side posts provided at the side edges of the rear sight.

In testimony whereof I aifix my signature in presence of two witnesses.
